True or False? If one of the angles of a triangle is obtuse, then the triangle is obtuse.

The five consecutive integers are -2, -1, 0, 1 and 2.

Given that;

The sum of five consecutive integers equals 5.5 times the middle integer.

Since the integers are consecutive, let the integer be;

x, x+1, x+2, x+3 and x+4.

Now, sum of the integers equals 5.5 times the middle integer.

Middle integer is x+2.

Hence we have;

x + x+1 + x+2 + x+3 + x+4 = 5.5( x+2 )

x + x+1 + x+2 + x+3 + x+4 = 5.5x + 11

We collect like terms

x + x + x + x + x - 5.5x = 11 - 1 - 2 - 3 - 4

5x - 5.5x = 1

-0.5x = 1

x = -( 1 / 0.5 )

x = -2

Since our integers are; x, x+1, x+2, x+3 and x+4.

We substitute in the value of x

x = -2

x+1 = -2 + 1 = -1

x+2 = -2 + 2 = 0

x+3 = -2 + 3 = 1

x+4 = -2 + 4 = 2

Therefore, the five consecutive integers are -2, -1, 0, 1 and 2.

Answer:

46

Step-by-step explanation:

For the value of y, substitute x = 28 into the equation.

2x + 3y = 194

2(28) + 3(y) = 194

56 + 3y = 194

3y = 194 - 56

3y = 138

dividing bothsides by 3

y = 46

Answer:

y = 46

Step-by-step explanation:

We want to find the value of y

2x+3y = 194

We are given the value of x

x=28

Substitute the value of x into the first equation

2(28)+3y = 194

56 + 3y = 194

Subtract 56 from each side

56+3y -56 = 194 -56

3y = 138

Divide each side by 3

3y/3 = 138/3

y =46

Due to length restriction we kindly invite to check the explanation for further details about the analysis of three quadratic equations and inherent rigid transformations.

Herein we find the graph of the parent quadratic equation f(x) = x² and two proposed resulting functions, whose difference with the former one have to be explained in terms of the kind of rigid transformations they have.

By comparing them, we find that both functions g(x) and h(x) are the result of a rigid transformation of the form f'(x) = k · f(x), where the transformation is a simple vertical dilation for k > 1, simple vertical contraction for 0 < k < 1, vertical contraction and reflection around the x-axis for - 1 < k < 0 and vertical dilation and reflection around the x-axis for k < - 1.

Function g(x) is the result of dilating f(x) by a factor of 3 and function h(x) is the result of dilating and reflecting f(x) around the x-axis by a factor of - 3.

The tables for each quadratic function are summarized below:

g(x):

 x             - 2             - 1               0             1                2

g(x)            12               3              0             3               12

f(x):

 x             - 2             - 1               0             1                2

g(x)          - 12            - 3               0           - 3            - 12

Lastly, we prepare the graph with the three functions in the image attached below.

If the mean is 382 and standard deviation is 97 then according to empirical rule 50% students scored  between 285 and 479 on the exam.

Given mean of 382 and standard deviation of 97.

We have to calculate the percentage of students scored between 285 and 479 on the exam.

Percentage is a number or ratio that is expressed in terms of 100.

We have to use z statistic in this question.

z=X-μ/σ

where μ is mean and

σ is standard deviation

from 285 to 382

z=285-383/97

=-1

p value =0.1587.

From 382 to 479

z=479-382/97

=97/97

=1

p value =0.3413

Total probability from 285  to 382 is 0.3413+0.1587=0.5

Percentage=5/10*100

=50%

Hence the percentage of students scored between 285 and 479 is 50%.

Combining the equations, the solution to the system of equations is: x = 3, y = 10.

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the equations are:

Combining(adding) them, we have that:

5x - 3y = -15.

From the second equation:

y = 3x + 1.

Replacing in the combined equation:

5x - 3(3x + 1) = -15.

-4x = -12

x = 3.

y = 3x + 1 = 3 x 3 + 1 = 10.

The length and width of the computer monitor is 23.36 inches

and 13.14 inches.

According to the given statement

we have given that  

The length of diagonal of rectangular monitor = 27 inches

The length to width ratio is 16:9

So , Let the Length of monitor = 16x

and The Width of monitor  = 9x

And we have to find the length and width of the computer monitor.

So, For this purpose,

From Pythagoras theorem

(Diagonal)² = Length² + width²

Put the values in it and then

27² = (16x)² + (9x)²

729 = 256x² + 81x²

After solving we get

337x² = 729

So, x² = 2.16

∴  x =  = 1.46 inches

So, The length = 16x = 23.36 inches

And The width = 9x = 13.14 inches.

Hence, The length and width of the computer monitor is 23.36 inches

By utilizing the law of the sines and Heron's formula, we find that the approximate area of the triangle is approximately 73.1 square centimeters. (Correct choice: A)

Prior to using Heron's formula, we must find the lengths of the missing sides by law of the sines:

A = 180° - 95° - 35°

A = 50°

[tex]b = 14\,cm \times \frac{\sin 35^{\circ}}{\sin 50^{\circ}}[/tex]

b ≈ 10.483 cm

[tex]c = 14\,cm \times \frac{\sin 95^{\circ}}{\sin 50^{\circ}}[/tex]

c ≈ 18.206 cm

Now, we proceed to calculate the area of the triangle:

s = 0.5 · (14 cm + 10.483 cm + 18.206 cm)

s = 21.345 cm

[tex]A = \sqrt{(21.345\, cm) \cdot (21.345\, cm - 14\,cm)\cdot (21.345\, cm - 10.483\,cm)\cdot (21.345\,cm - 18.206\,cm)}[/tex]

A ≈ 73.113 cm²

By utilizing the law of the sines and Heron's formula, we find that the approximate area of the triangle is approximately 73.1 square centimeters. (Correct choice: A)
